Ancillary Testing
Ultrasound biomicroscopy (UBM) revealed an iris cyst originating from the original wound. The cyst appeared to be adherent to the surrounding cornea. Figure 4 shows the cyst separating the anterior and posterior layers of the iris. Figure 5 shows the extent of the cyst near the ciliary body; note this image is from the peripheral portion of the cyst, since at the wound the differentiation of cyst and ciliary body was difficult to view. Figure 6 shows the full extent of the cyst in the anterior-posterior direction, which measured 3.80 microns.
